Description Modbus logo

The Modbus protocols allows the exchange of data with a wide range of industrial devices and many supervisors. The Modbus 2 library from Engiby sàrl supports the following Modbus protocols:

  • ASCII + RTU over serial lines RS 232, 422 and 485
  • TCP + UDP over Ethernet

Both, master and slave functions are included in the library and several master and several slave drivers can run simultaneously on the Saia PCD®.
The library is available in form of S-Fup FBoxes for Fupla programmers. For the use in IL or Graftec the library provides an interface using FBs which can be called. For a detailled description of the features and Getting Started examples follow this link.

 

The Modbus library is now available with the NG-Configurator and Excel. It is especially useful for big projects. The NG-Configurator allows you to define a long list of sending and receiving transmissions in an Excel file instead of placing Fboxes in a Fupla file. Each transmission can have different parameters like, an enable flag, a single or cyclic mode, different modbus functions, a format conversion, etc. You also have the possibility to retrieve a large amont of data in one single transmission to a buffer and then spread them in different flags and registers using different format conversions.
